A device (10) for winding a film comprises a winding unit (13) to wind a predetermined amount of films (11) at various speeds; an unwinding unit (12) to unwind the film (11) which is wound on the winding unit for a predetermined amount; and an accumulate unit (30) to accumulate and unwind the film (11) which is being unwound from the unwinding unit to the winding unit. The accumulate unit (30) changes the accumulation of the film (11) to correspond to the change of the winding unit (13) in speed for winding the film (11). The accumulate unit (30) includes a pair of fixed rollers (31, 32) installed on the returning path of the film (11); a movable roller (33) which is moved in the direction perpendicular to the returning path of the film (11) through a space between the pair of rollers (31, 32); and a servo motor (34) to move the movable roller (33). |
